Identification of Problem
Existing system with limitations :-
The existing system was having a number of difficulties regarding maintaining the record
of information , records of there grades in various subjects(in both minor exams and
major xams) , Student Management.
First of all our focus will be on the manual system for Student Management. One
can observe that for the whole process of all the record of information , records of
there grades in various subjects(in both minor exams and major xams) and it tell us
about the performance of the student whether it is poor, excellent, satisfactory etc
, one organization needs to recruit too many staffs to handle the specific duty.
Second is the efficiency, time elapsed and the human errors involved.
Finally Beside these the most important is the data storage, searching for a
particular record, transferring the data to its various networks and data piracy.

Front End remains on client side. Front end is made for end user who uses
our application. Basically in front end our input-output forms reside which
takes the input from the client and gives output back to client.
INTRODUCTION VISUAL BASIC (FRONT END)
Why Visual Basic-6:
Visual Basic-6 has emerged as one of the standard Windows Programming Language
and it has become a must for all Software people for developing Applications in Visual
Environment.
What is Visual Basic-6?
Visual Basic-6 has its origin in Basic which was developed round about the year 1960,
when high level languages were just being introduced to the computer community.
Microsoft has made it extremely powerful by gearing all its good features to the Windows
environment. Starting with the version 3 and then with 4, and then with 6, Visual Basic is
now at version 6. Basic is a Procedure Oriented Language intended to implement single
tasks in text based environment whereas Visual Basic is an Event Driven Language
STUDENT MANAGEMENT SYSTEM
23
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
intended to implement Projects or Applications containing multiple tasks in Windows
Environment.
What can Visual Basic do for you?
Visual Basic can serve as an ideal front end tool for the clients to interact. It has got
connectivity mechanisms for all types of databases situated far and wide in a network and
so it can cater to the needs of a large body of clients. Using the latest ActiveX
technologies, it can integrate the functionalities provided by other applications like Word
Excel and other Windows. Its internet capabilities provide easy access to documents and
applications across the internet. Above all it embodies the Object Oriented Technology,
which is the cutting edge technology for all the present day developments in the Software
World. The final application is a true EXE file and so can be freely distributed.
Structure of VB-6 Projects:
We said earlier that VB-6 implements projects or applications. A project is developed
using one or more Forms. A Form is simply a window containing one or more Controls.
Controls in VB consist of labels, text boxes, list boxes, combo boxes, scroll bars etc. which
are the constituents of windows environment. It is only the controls that give VB, its
immense power and so there is a lot of interest in creating more and more powerful
controls. ActiveX controls mark a significant development in controls technology. In fact all
controls in VB-6 are ActiveX controls, which have the extension .ocx. These controls have
properties whose values can be initialized at design time and also varied during run time.
The properties are something like variables. The controls are activated by codes written in
STUDENT MANAGEMENT SYSTEM
24
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
a high level language. By associating our problem variables with the properties of the
controls, our problem variables can be manipulated to give the problem solution. In
summary we can say that a VB project is made of forms, controls and their properties and
codes.
Integrated Development Environment:
The working environment in VB is often referred to as the Integrated Development
Environment or IDE, because it integrates many different functions such as design, editing,
compiling and debugging within a common environment. Since all our projects are
developed only in the IDE, let us now have a brief look at its features. You will be able
to understand their uses at the time of building projects. The VB IDE looks as shown in
the figure
Elements of Visual Basic IDE:
The VB IDE consists of the following elements.
1. Menu Bar
2. Context Menus
3. Toolbars
4. Toolbox
5. Project Explorer Window
6. Properties Window
7. Object Browser
8. Form Designer ETC.
STUDENT MANAGEMENT SYSTEM
25
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Menu Bar:
Menu Bar displays the commands you use to work with Visual Basic and is located at
the top. Besides the standard File, Edit, View, Windows and Help menus, menus are
provided to access functions specific to programming such as Project, Format or Debug.
Context Menus:
Context Menus provide certain short cuts to frequently performed actions. To open a
context menu, click the right mouse button on the object you are using. The specific list
of shortcuts available from context menus depends on the part of the environment where
you click the right mouse button. For example, the context menu displayed when you
right click on the Toolbox lets you display the components dialog box, hide the Toolbox,
dock or undock the Toolbox, or add a custom tab to the Toolbox etc.
Toolbars:
Toolbars provide quick access to commonly used commands in the programming
environment and is located below the menu bar. You click a button on the toolbar once
to carry out the action represented by that button. By default, the Standard toolbar is
displayed when you start VB. Additional toolbars, for editing, form design, and debugging
can be toggled on or off from the Toolbars command on the View Menu. Toolbars can be
STUDENT MANAGEMENT SYSTEM
26
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
docked beneath the menu bar or can “float” if you select the vertical bar on the left edge
and drag it away from the menu bar.
Toolbox:
Toolbox provides a set of controls that you use at design time to place them on the
form and is located on the left side. In addition to the default controls layout, you can
create your own custom layouts by selecting Add Tab from the context menu and adding
controls to the resulting tab.
Project Explorer Window:
The Project Window lists the forms, and modules in your current project. To
recapitulate, a project is simply a collection of files you use to build your application.
Properties Window:
Properties Window displays the different properties of the different objects, such as
size, caption, color etc., which can be set at the design time and located at the right side.
Object Browser:
The Object browser lists the available objects in your project, and gives you a way to
navigate through your code. You can use the Object browser to explore objects in VB ,
STUDENT MANAGEMENT SYSTEM
27
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
see what methods and properties are available for those objects, and paste code
procedures into your application.
Form Designer:
The Form serves as the designer window or the container for placing the different
controls, graphics and pictures needed for your applications and is located at the center.
There can be more than one form or a designer window for a single application.
SDI or MDI Interface
Two different styles are available for the Visual Basic IDE: single document interface
(SDI) or multiple document interface (MDI). With the SDI option, all of the IDE
windows are free to be moved anywhere on screen; as long as Visual Basic is the
current application, they will remain on top of any other applications. With the MDI
option, all of the IDE windows are contained within a single resizable parent window.
To switch between SDI and MDI modes
1. Select Options from the Tools menu.
The Options dialog box is displayed.
2. Select the Advanced tab.
3. Check or uncheck the SDI Development Environment check box.
The IDE will start in the selected mode the next time you start Visual Basic.
STUDENT MANAGEMENT SYSTEM
28
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
– or –
Run Visual Basic from the command line with a /sdi or /mdi parameter.
Docking Windows
Many of the windows in the IDE can be docked, or connected, to each other or to
the edge of the screen. These include the Toolbox, Form Layout Window, Project
Explorer, Properties window, Color Palette, and Immediate, Locals, and Watch
windows.
To dock or undock a window
1. Select the window you wish to dock or undock.
2. Drag the window to the desired location by holding down the left mouse button.
The outline of the window will be displayed as you drag.
3. Release the mouse button.
Creating an Application or a Project:
Let us now wet our hands by actually creating an application using the IDE. Creating
any VB application consists of only three steps.
1. Create the interface by placing the required controls in the form window.
2. Set Properties to the controls using the Properties window of each control.
3. Write codes to manipulate the properties of the controls in the Code Window.
You start VB by clicking the start button on the task bar.
Controls used in this Project:
STUDENT MANAGEMENT SYSTEM
29
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
We use five command buttons and one text box in this project. For drawing a control
in the form window, double click on the appropriate control. The control with default
characteristics is brought into the form. It can be dragged and resized according to your
requirements. Drag the above mentioned 6 controls from the Toolbox and position them.
Of course you can size and position them according to your liking.
Setting the Properties of the Controls:
Each control has a separate Properties window. The Properties window will be
normally visible on the right side. If it is not visible it can be opened by clicking
‘Properties Window’ from the View menu after selecting the required control. We can
initialize the properties like size, caption, color etc. by selecting the desired values using
the drop-down menu for the controls as well as the properties. The Text property of the
text box is given blank. We simply retain the names of the other controls as they are.
Creating an EXE File:
After completing all the files for a project, you can convert the project into an
executable file(.exe) by selecting ‘the make project.exe’ command from the file menu.
An EXE file can be executed outside VB environment and so can be freely distributed.

MICROSOFT ACCESS DESCRIPTION (Back end)
Microsoft Access is a powerful program to create and manage your
databases. It has many built in features to assist you in constructing and viewing your
information. Access is much more involved and is a more genuine database application
than other programs such as Microsoft Works.
First of all you need to understand how Microsoft Access breaks down
a database. Some keywords involved in this process are: Database File, Table, Record,
Field, Data-type. Here is the Hierarchy that Microsoft Access uses in breaking down a
database.
Database File: This is your main file that
encompasses the entire database and that is
saved to your hard-drive or floppy disk. Example)
StudentDatabase.mdb
Table:A table is a collection of data about a specific
topic. There can be multiple tables in a database.
Example #1) Students. Example #2) Teachers
Field:Fields are the different categories within a Table.
Tables usually contain multiple fields. Example #1)
Student LastName. Example #2) Student FirstName
Datatypes:Datatypes are the properties of each field. A
field only has 1 datatype.

Paradigm
STUDENT MANAGEMENT SYSTEM
36
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Software Engineering Paradigm:-
The basic objective of software engineering is to: develop methods and procedures for
software development that can scale up for large systems and that can be used to
consistently produce high quality software at low cost and with a small cycle time. That is,
the key objectives are consistency, low cost, high quality, small cycle time, and scalability.
The basic approach that software engineering takes is to separate the development
process from the software. The premise is that the development process controls the
quality, scalability, consistency, and productivity. Hence to satisfy the objectives, one must
focus on the development process. Design of proper development process and their
control is the primary goal of the software engineering. It is this focus on the process that
distinguishes it from most other computing disciplines. Most other computing disciplines
focus on some type of the product-algorithms, operating systems, databases etc. while
software engineering focuses on the process for producing products.
To better manage the development process and to achieve consistency, it is essential that
the software development be done in phases.

AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Different Phases Of The Software Development Life Cycle (SDLC):
1) Requirement Analysis:
Requirement analysis is done in order to understand the problem the software system is
to solve. The problem could be automating an existing manual process, developing a new
automated system, or a combination of the two. The emphasis in requirements analysis is
on identifying what is needed from the system, not how the system will achieve its goals.
There are at least two parties involved in the software development-a client and a
developer. The developer has to develop the system to satisfy the client’s needs. The
developer does not understand the client’s problem domain, and the client does not
understand the issues involved in the software systems. This causes a communication gap,
which has to be adequately bridged during requirements analysis.
2) Feasibility Study :
A feasibility study is conducted to select the best system that meets performance
requirement. This entails an identification description, an evaluation of candidate system
and the selection of best system for he job. The system required performance is defined
by a statement of constraints, the identification of specific system objective and a
description of outputs.
The key consideration in feasibility analysis are :
STUDENT MANAGEMENT SYSTEM
39
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Economic Feasibility
Technical Feasibility
Operational Feasibility
Economical:-
The proposed system is economically feasible because the cost involved in purchasing
the hardware and the software are within approachable. The personal cost like salaries of
employees hired are also nominal, because working in this system need not required a
highly qualified professional. The operating-environment costs are marginal. The less time
involved also helped in its economical feasibility.
Software Cost :
Visual Basic 6.0 : 25000/-
MSaccess : 15000/-
Manpower :
Team cost : 15000/-
System Cost : 20,000/-
Total Cost : 75000/-
Technical :-
Hardware’s used in this project are- Preferably Pentium III/Celeron/AMD based
system, 32MB RAM, 20 GB HDD, alongwith Dot-Matrix/Laser jet printer. These hardware
were already available on the existing computer system. The software like VB 6.0,MS -
WORD and operating system WINDOWS-98’ used were already installed On the existing
STUDENT MANAGEMENT SYSTEM
40
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
computer system. So no additional hardware and software were required to purchase and
it is technically feasible.
Tools Used :
1) ADO Library 2.1
2) Windows Common Control 6.0
3) Data Report
4) Visual Basic 6.0
5) MSaccess.
Duration:-
For study- 5days,
For designing- 20days,
For development- 20 days,
Testing- 5 days,
Total time- 50 days.
Operational :-
The analyst considers the extent the proposed system will fulfill his Department’s.
That is whether the proposed system covers all aspects of the working system and
whether it has considerable improvements. We have found that the proposed
“Personal Information” will certainly have considerable improvements over the
existing system.
STUDENT MANAGEMENT SYSTEM
41
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
3) Software Design:
The purpose of the design phase is to plan a solution of the problem specified by the
requirements documents. This phase is the first step in moving from the problem domain
to the solution domain. Starting with what is needed; design takes us toward how to
satisfy the needs. The design of a system is perhaps the most critical factor affecting the
quality of the software. It has a major impact on the later phases, particularly testing and
maintenance.
The design activity is divided into two phases: System Design and Detailed Design. In
system design the focus is on identifying the modules, whereas during detailed design the
focus is on designing the logic for each of the modules.
4) Coding:
The goal of the coding phase is to translate the design of the system into code in a given
programming language. Hence during coding, the focus should be on developing programs
that are easy to read and understand, and not simply on developing programs that are
easy to write.
5) Testing:
Testing is the major quality control measure used during software development. Its basic
function is to detect errors in the software. Testing not only uncover errors introduced
STUDENT MANAGEMENT SYSTEM
42
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
during coding, but also errors introduced during the previous phases. Thus, the goal of the
testing is to uncover requirement, design and coding errors in the programs. Therefore,
different levels of testing are used. Testing is an extremely critical and time consuming
activity. It requires proper planning of the overall testing process. The output of the
testing phase is the test report and the error report.
6) Operation & maintenance phase:
Software maintenance is a task that every development group has to face, when the
software is delivered to the Client‘s site, installed and is operational. Software
maintenance is a very broad activity that includes error correction, enhancement of
capabilities, deletion of obsolete capabilities and optimization.

Overview of System Design
Software design is both a process and a model. The design process is a set
of iterative steps that enable the designer to describe all aspect of software to be built and
overall commitment to quality are critical success factor for component design.
The design model is the equivalent of an architect’s plan for a house. It begins by
representing the totality to be built and slowly refines the things to provide quittance for
constructing each details. Similarly, the design model that is created for software provides
a verity of different views of the computer program.
The design should be traceable to the analysis model.

DATA FLOW DIAGRAMS (DFD’S)
As information moves through software, it is modified by a series of
transformation. A data flow diagram (DFD) is a graphical technique that depicts
information flow and the transformation that is applied as data moves from input to
output.
The data flow diagram may be used to represent a system or software at any level of
abstraction. Infect, DFD’s may be partitioned into levels that represent increasing
information flow and functional details. Therefore, the DFD provides a mechanism for
functional modeling as information flow modeling.

Symbols:-
In DFD, there are the following symbols used.
1. Rectangle:-
A Rectangle defines a source or destination of the system data.
2. Row:-
An arrow identifies data flow – data in motion. It is a pipeline through which information
flows.
3. Circle:-
A cycle or bubble represents a process that transforms incoming data flows into outgoing
data flows.
4. Open Rectangle:-
An open rectangle is a data source i.e. data is rest, or a temporary repository of data.

OPTIMIZATION
STUDENT MANAGEMENT SYSTEM

AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Coding Optimization:-
Optimization refers to increase in the throughput of the system with minimal use
of effort and system resources. It also includes faster response through better system
design practices including optimal utilization of code, normalized database structures
and their use in the code.
The very first instance that stands for optimization of this
application is the choice of the second alternative of the Feasibility study, that is, as
specified earlier would prove to be most favorable and best possible for the progress in
the working of the company. The other criteria that ensure the optimization of this
software application are enlisted as under
Use of modular design structure of application development.
Use of Normalized Database Structures-Database Optimization.
Use of code modules extensively-Code Optimization.
Use of minimum number of code lines for maximum processing of input data.
Allocating / de-allocating memory for the objects used in the code as and when
required. – Garbage collection
Re-use of similar input forms/output reports wherever necessary to reduce the
overall size of the application.
We find optimal solution of a project that is cost effective as well as time
effective. Both are equally important for a project we divide the project into modules so
that we can easily understand the project. And also it will take less time to solve the
problems. Modularity is the single attribute of software that allows a program to be
intellectually manageable.

TESTING
STUDENT MANAGEMENT SYSTEM
55
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Introduction of Testing
Testing objectives: Testing is mainly done for rectifying the error from the program that is
design for particular problem.
1. Testing is a process of executing a program with the intent of finding an error.
2. A good test case is one that has a high probability of finding an as-yet UN
discovered error.
3. A successful test is one that uncovers an as-yet undiscovered error.
If Testing is conducted successfully (according to the objectives stated previously), it will
uncover error in the software.
Testing Principle: Before doing the Testing some point kept in mind
All tests should be traceable to customer requirement.
Tests should be planned long before testing begins.
The Pareto principle should be applies to software testing. (It means that 80
percent of all error uncovered during testing will likely be traceable to 20 percent
of all program component.
Testing should be begin in “small” and progress toward large.
Exhaustive testing is not possible.
To be most effective, testing should be conducted by an independent third party.

TESTING AND DEBUGGING
After programming the program has many logical errors we test our system
program our system does not run successfully and does not achieve the user‘s
requirement. If the user requirement cannot be fulfilled, we use the debugging tools in
the project and debug our project in statements by statements and found error and
correct the testing process focusing on logic internals of the software, ensuring that all
statements have been tested.
Dummy data can be used with varying access levels to make sure that everyone has
access the right functions and information and cannot access what they should not.
FUNCTION TESTING
System design may have so many functions. Each program has been defined into number
of function. Each function has its own task. We can each function to perform an accurate
result. We must debug each function.
Function is a block of code that performs a particular task, returns a particular value.
STRUCTURAL TESTING
Each program has a structure, and contains the function, variable, controls, statement,
decision-making loops. We can test program structure these are defined properly in our
program. So the programmer set the structure of the program.
STUDENT MANAGEMENT SYSTEM
57
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
COMBINING STRUCTURAL AND FUCTIONAL TESTING
After testing in our program function make the setup of the programs so that each
function is run according to definition to the structure.
Program may have several structure and functions. Programmer can arrange these
method and structures. These properly perform our task.
Testing the Plan:I test the statement that are used in the project like if, switch case,
Looping statement like for, while, until etc.

Condition Testing: Condition Testing is a test case design method that exercises the logical
conditions contained in a program module.
Loop Testing: Loops are mainly used in all the module of the project, there are different
type of loops in the project that I use.
Simple loops: In the simple loop in which the statement is executed inside the single loop.

Nested loops: The number of test are required then nested loop are used in this case one
is the inner loop and other is outer loop firstly control goes into the outer loop then goes
into the inner loop after finishing the inner loop in return into the outer loop.

AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Concatenated loops: Concatenated loops can be tested using the approach defined for
simple loops, if each of the loops is independent of the other. However, if two loops are
concatenated and the loop counter for loop 1 is used as the initial value for loop 2 then
the loop are not independent. When the loops are not independent, the approach applied
to nested loops is recommended.

Testing the Documentation: Test the entire document that is designed for the project
there are some point kept in mind.
Does the documentation accurately describe how to accomplish each mode of
use?
Description of each interaction sequence is accurate.
Examples are accurate or not.
Terminology, menu description, and others things are documented according to
requirement o client.
Troubleshooting can be accomplished easily with the documentation.
The document table, contents and index accurate and complete.
The error message displayed for the user is properly and detailed defined in the
documentation.
Links are accurate and complete in the project or not.

Testing Procedure:
Unit Testing: After the coding step we do the unit test for project in this test we check the
project as unit wise. Full project is dividing into number of modules so we check every
module separately in this testing we use driver and stub mainly for testing.
Driver and stub are the software. In the application program driver is only as a main
program and stub is stub serve to replace modules that are subordinate the component to
be tested.

Integration Testing: Integration testing is a systematic technique for constructing the
program structure while at the same time conducting tests to uncover errors associated
with interfacing. The objective is to take unit tested components and build a program
structure that has been dictated by design. There are two type of integration testing
1. Top down integration
2. Bottom up integration
Top-down Integration: Top down integration testing is an incremental approach to
construction of program structure. Modules are integrated by moving downward through
the control hierarchy, beginning with the main control module (main program). They are
incremented in the depth first or breadth first manner.

Bottom-up Integration: Bottom up testing is beginning with atomic modules. In this
testing low level component are taken firstly and combined into a cluster and check it.

System testing:
System testing is actually a series of different tests whose primary
purpose is to fully exercise the computer based system. Although each test has different
purpose, all work to verify those system elements have been properly integrated and
perform allocated functions. Types of system testing are following:-
STUDENT MANAGEMENT SYSTEM
70
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
1. Recovery Testing
2. Security Testing
3. Stress Testing
4. Performance Testing
Recovery Testing: Recovery testing is a system test that forces the software to fail in a
variety of ways and verify that recovery is properly performed. If recovery is automatic,
reinitialization, check pointing mechanisms, data recovery and restart are evaluated for
correctness.
Security Testing: Security testing attempts to verify that protection mechanism built into a
system will, in fact, protect it from improper penetration.
Stress Testing: Stress testing executes a system in a manner that demands resources in
abnormal quantity or volume. Like test case may require maximum memory or other
resources are executed.
Performance Testing: Performance tests are often coupled with stress testing and usually
require both hardware and software instrumentation.
Here the system testing involved is the most widely used testing process consists of five stages as
shown in the figure. In general, the sequence of testing activities is component testing, integration
testing then user testing. However, as defects are discovered at any one stage, they required
program modifications to correct them and this may required other stages in the testing process
to be repeated.

AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
VALIDATION CHECKS:-
Developing project has number of phases; we have to under go each phase in order
to successfully complete the whole project. Different steps which we have to follow in
order for successfully completion of project are:-
Analyzing-
Making up of Project Synopsis and Documentation - In this phase we do paper work,
write the client requirement and design database according to the requirement of client.
After that we divide the whole project into different modules and assign task to the
Project members.
Coding –
In this phase we actually practically implement paper work and do the front end and
back end programming part.
Testing –
This is the most important phase of the Project where we practically check our code
in different situations i.e. weather it is working in different conditions or not , weather it is
solving the objectives of client. During this phase only we do rectification job.
The most important technique used in Testing is “Trial and Error System”. We will be
discussing this in detail later. Incorporating - Incorporating means loading the application
on to the server from where it will be used by the client machines.
Training –

After incorporating the code on to the client machine we have to provide training to
the employees of the client i.e. how to use this software and if there is any problem they
can do verification part.
We all these phases here we will be discussing Testing Part i.e. Validation Checks. As
already told one of the most important technique of Testing is “ Trial and Error System “ In
this system we put our code to different conditions to check that weather it is working
properly or not. We also have adopted this technique. We have done data verification by
entering wrong data type in our data base to test weather it is working properly. We tried
to search records from different tables using Primary Key i.e. particular ID and checked
weather it is fetching correct record or not. We have tested weather proper records
according to proper fields are inserted to the tables or not.

AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
SYTEM SECURITY
There are basically two types of security associated with this system:-
1. Physical security:-
Damage due to natural causes like earth tremor, flooding, water logging, fire hazards,
atmospheric or environmental conditions etc for overcoming these difficulties the replica
of the data are automatically stored at various networks and for environmental conditions
Air conditioning environment is created.
2. Data security:-
There are basically two problems associated with data security:-
A). Data not being available to the authorized person at the time of need.
b). Data becoming available to the unauthorized person.
To overcome these difficulties the following access facilities has been provided:-
I) Identification:- Unique Ids for the different users have been provided.

ii) Authentication:- System checks the password under the particular user
identification. The computer Permits the various resources to the authorized person.
iii) Authorization:-
The access control mechanism to prevent unauthorized logging to the system.
CONCLUSION

Conclusion:-
This application is prepared for the established AMITY UNIVERSITY,
UTTAR PRADESH and it will provide almost full information about how to manage the
grades or the information of the student. The both utilities provided make the application
attractive and easy in getting information. After implementing the application It will
contain the advantages were incomparable to the present contemporary systems used by
company. The most admirable feature founded was its simplicity in terms of application to
the user but its highly beneficial outputs can’t be ignored. The users will be highly
benefited after using the system.

FUTURE SCOPE
STUDENT MANAGEMENT SYSTEM
193
AMITY INSTITUTE OF INFORMATION TECHNOLOGYAMITY UNIVERSITY
Future Scope and Limitations:-
LIMITATIONS:-
Since, every system has some limitations so our proposed system is also not untouchable
in this regard. Although it includes every kind of features but it can’t be used in a huge
organization where number of networks are very large, because the data base used in this
system is an average one. Also it doesn’t have different kind of access feature for different
users.
SCOPE FOR FUTURE WORK :-
Since this system has been generated by using Object Oriented programming, there are
every chances of reusability of the codes in other environment even in different
platforms. Also its present features can be enhanced by some simple modification in the
codes so as to reuse it in the changing scenario.

Keyword used in this project
Textbox
A text Box control, sometimes called an edit field or edit control, displays information
entered at design time, entered by the user, or assigned to the control in code at run time.
Button
Use a Command Button control to begin, interrupt, or end a process. When chosen, a
Command Button appears pushed in and so is sometimes called a push button.
List Box
A List Box control displays a list of items from which the user can select one or more. If
the number of items exceeds the number that can be displayed, a scroll bar is automatically
added to the List Box control.
Label
A Label control is a graphical control you can use to display text that a user can’t change
directly.

Frame
A Frame control provides an identifiable grouping for controls. You can also use a Frame
to subdivide a form functionally – for example, to separate groups of Option Button
controls.
Combo Box
A Combo Box control combines the features of a text box and a list box. This control
allows the user to select an item either by typing text into the combo box, or by selecting it
from the list.
Option Button
An Option Button control displays an option that can be turned on or off.
Check Box
A Check Box indicates whether a particular condition is on or off. We use check boxes in
an application to give users true/false or yes/no options. Because check boxes work
independently of each other, a user can select any number of check boxes at the same time.
